c STOVE FOB :BURNING BUBBISH Application led October 10, 1929. Serial No. 398,754.

This invention relates to rubbish-burning.

l AA further and more specific object of the invention is the production in a construction of this character of an arrangement permitting very economical manufacture while still retaining. the durable characteristic desir- '20 able in such devices.

A still further object of the invention is to produce a stove of this character which will be entirely odorless in operation and which will insure a rapid and efficient reduction of material disposed therein.

A still further obj ect of the invention is the production in a device of this character of an arrangement rendering the structure proof against the minor explosions common to trash incinerators.

These and other objects are obtained by the construction shown in the accompanying drawings wherein, for the purpose of illustration, have shown a preferred embodiment of my invention and wherein:

Fig. 1 is a side elevation of a trash-burning stove constructed in accordance with my invention;

Fig. 2 is a vertical sectional view therethrough;

Fig. 3 is a section on line 3-3 of Fig. 2; and

Fig. 4 is a section on the line 4-4 of Fig. 2.

Referring now more particularly to the drawings, the casing 0f the stove may be generally divided into a base, fire-box and dome sections indicated at 10, 11 and 12, respectively. The fire-box section will be provided with the usual clean-out opening 13 controlled by a door 14 and has arranged in .the upper end thereof a removable grid or spider 15. One arm 16 of this spider hask depending therefrom bearings 17 within which is rotatably mounted a shaft 18, the outer end of which projects through the wall of the ash-pit section and is squared for the reception of a shaker wrench, as at 19. In the junction of the arms off the spider, a vertically-extending shaft 20%` is journaled. The lower end of this shaft is provided with a bevelled gear 21 meshed wlth a bevelled gear 22 secured to the inner end of the shaft 18.

Intermediate their ends, arms 16 are connected by a circular reinforcing rib 23 which 65 forms a seat for the lower end of a conical member or base 24. Lugs 25 carried by thev brace 23 and, engaging the inner face of the wall of the conical member, maintain this member against transverse displacement upon its seat. The upper end of shaft 20 is journaled in the apex of the conical member, as indicated at 26, and projects therethrough to permit attachment thereto of a shank 27 of a blade 28 which upon rotation of shaft 75 20, sweeps the upper surface of the conical member.

The lower edge of the base conical member has extending outwardl and upwardly therefrom radially-directe arms 29, the outer ends of which form seats for the lower ends of vertically-extending bars 30 and are formed with sockets 31 for the reception of lugs produced on the lower ends ofthese bars, so that these ends may be held against transverse displacement. The upper end of the lire-box section has secured thereto, at the inner face of its wall, an annular band 32, this band having its upper edge oli'set inwardly, as at 33, so that it combines with the wall to produce an annular verticallydirected groove. The upper ends of bars 30 each have an upwardl and outwardly arching extension 34, which is adapted to engage in a notch 35 formed in the wall of the 95 offset portion. Each extension has at its .end a T head 36 for engagement in the groove. It will be obvious that these bars may be readily removed upon removal of the dome section and are capable of a limited 10 vertical movement, such as would occur when the bars are l eating or cooling, without becoming detached from their engaged suport. P The dome 12 is provided in its side wall with a door 37 through which refuse may be inserted in the upper end of the basket formed by the conical member 24, its arms 29, bars and their extensions 34,'and at its upper end with a flue outlet 38. The extensions 34 pre- 1 vent the refuse from falling into the space between the basket and walls of the shell, so that the material to be burned will be at all times contained within the basket and may be very rmly packed therein. The mass of rubbish may be ignited by a match dropped through the door 37 from the top thereof and, in burning, will cause an intense draft upwardly along the sides of the basket with the result that the walls of the fire-box section 11 will not be highly heated and the radiation surface of the stove will accordingly' be materially reduced. In the event that any explosion occurs, as is often the case in burning refuse due to the inclusion in the rubbish placed therein of bits of celluv loid or the like, the door 37, which embodies no fastening means, will open, relieving the pressure and preventing the destruction of the apparatus. Burned rubbish which remains within the basket may be readily discharged therefrom to the ash pit by rotation of blade 28 and, at this time, the door 14 may be closed, so that no dirt or dust can pass from the stove. v

Since the construction employed is obviously capable of various arrangements and modifications without departing from the spirit, I do not wish to limit myself thereto except as hereinafter claimed.`

I claim: l Y

1. In a rubbish-burning stove, a casing having a flue outlet at its upper end,'a sup port within the easing adjacent the'lower end thereof, a base carried by the support, vertically-extending arms carried by said base and arranged in spaced relation to the side walls of the casing, extensions upon the upper ends of said arms engaging the casing walls, a door in the casing permitting the introduction of rubbish to the lirepot provided by said base and arms,.and means -for admitting air to the lower end of the casing, the extensions of said arms having engagement with the walls of the casing permitting movement thereof in a direction longitudinal to the arms while holding the same against transverse displacement.

2. Ina rubbish-burning stove, a casing having a flue outlet at its upper end, a support within the casing adjacent the lower end thereof,`a base carried'by said support, upwardly and outwardly inclining supports projecting radially from the periphery of said base, arms vseated at their lower ends upon the outer ends of said radial supports and extending forwardly in spaced relation to the side walls of the casing, extensions upon the upper ends of said arms engaging the casing walls, a door in the casin permitting the introduction of rubbish to tie irepot provided by said base and arms, and means for admitting air to the lower end of the and extending forwardly` in spaced relation,v

to the side walls of the casing, extensions upon the upper ends of said arms engaging the casing walls, a door in the casing permitlting the introduction of rubbish in the iirepot provided b said base and arms, and means for admitting air to the lower end of the casing, the lower ends of the arms having lugs, the outer ends of the radial supports having sockets for the reception of said lugs.
